<pre class="moz-quote-pre" wrap="">Hi everyone,
For the past few months I have been using Hadrian for the majority of my
GHC builds. In due course I have encountered a few papercuts:
* hadrian/cabal.build.sh is quite wordy (#16250); moreover, you need to
be in the source root to invoke it (#16667)
* editing hadrian.settings is quite difficult due to the lack of
availability of tab-completion in vim
* maintaining multiple build roots is quite error-prone since you must
remember which build flavour you used for each (#16481, #16638)
* there is no equivalent to setting `stage=2` in `mk/build.mk` to make
the stage-1-freeze persistent
To address these I cobbled together a small wrapper, hadrian-util. I
have this installed in my home-manager environment with a shell alias,
`hu`, meaning that building GHC is as easy as typing `hu run` anywhere
in the tree.
As discussed in the README, `hadrian-util` supports multiple build
roots, has a moderately convenient interface for manipulating
hadrian.settings (with completion!) and has enough persistent state to
eliminate most of the error-prone boilerplate from Hadrian invocations
without being confusing.
There is the question of what the long-term future of hadrian-util
should be. Arguably it is merely a hack papering over some of the
shortcomings of Hadrian's current UX; perhaps eventually these will be
fixed. However, in the meantime, I've found that hadrian-util makes
hadrian quite pleasant to use.
I hope others also find this useful.
Cheers,
- Ben
